Find each measurement indicated, round your answers to the nearest tenth

1. 27.0 m

2. 28.0 degrees

Step-by-step explanation:

1. AB

To find AB, we start by getting the measure of the third angle A

Mathematically;

A + 90 + 51 = 180

The sum of angles in a triangle is 180

A = 180-90-51

A = 39

We then proceed to use the sine rule

Mathematically, the sine rule states that the ratio of the measure of a side and the sine of the angle facing the side is same for each side of the triangle

Thus, with respect to the given triangle;

17/sin 39 = x/sin 90

x = 17sin90/sin 39

x = 27.0 m

Kindly note that we substituted x for AB

2. To find the measure of angle A we use the sine rule as used above, but here we have a missing angle and not a missing side

Thus;

34/sin 127 = 20/sin A

Sin A = (20 sin 127)/34

sin A = 0.469

A = sin^-1 0.469

A = 28.0 degrees
